A team from Massachusetts Institute of Technology (MIT) has recently developed a pioneering technique that allows 3D printing of glass at lower temperatures than traditional methods. This innovation represents a qualitative leap in the field of additive printing towards the production of advanced optical and electronic devices.
How the 3D glass printing process works
The new methodology is based on the technique of direct ink writing, or the layer-by-layer extrusion of an inorganic compound at room temperature. After printing, the object is heated in a mineral oil bath and cleaned with an organic solvent. The result is an inorganic silica structure, obtained at a temperature close to 250°C, decidedly more accessible than the 1000°C traditionally required for glass processing.
The potential of the material
In addition to reducing costs and energy impact, this technique promotes the production of complex shapes. 3D glass printing becomes an ideal solution for the creation of components in the biomedical, optoelectronic and microfluidic sectors.
The structures produced guarantee good thermal stability and excellent resolution. The research team is also working to improve the material's optical transparency and introduce inks that respond to electrical and chemical stimuli.
Currently, there are no commercial solutions for 3D glass printing yet. However, this Research It seems to lay the foundations for the diffusion of this solution which aims to overcome the problems of the materials used up to now such as metal and plastic.
